French market mishap

So this morning we went to the little French Market they have a couple of times a year in Wimbledon - very nice, got some bread, salami, sausages, and so on. Got home to realise that one of the items we bought at the deli stall wasn't in the bag (celeriac remoulade, which is kind of like coleslaw, only made with celeriac (celery root) and a bit of mustard in the mayonaise) - such an annoyance. It seems like a total waste of money not to go back and get it, but round trip to Wimbledon including having to park the car and whatnot is probably at least 40 minutes, so it's also a matter of what one's time is worth. So we decided not to go back. Missed it at lunch though. Oh well, at least I know how to make it and can make my own after I go grocery shopping. Doesn't stop it being annoying though.
